Description

Technical Field

[0001] This utility model relates to the field of adhesive tape viscosity testing technology, specifically a viscosity testing device for automotive wiring harness adhesive tape. Background Technology

[0002] As a key auxiliary material in the manufacturing process of automotive wiring harnesses, adhesive tape is mainly used for fixing, protecting, and insulating the wiring harnesses. Its viscosity properties directly affect the wrapping effect and service life of the wiring harnesses. Since there are many influencing factors in the production process of adhesive tape, such as the quality of raw materials, production process, and environmental conditions, the viscosity properties of the adhesive tape may fluctuate. Therefore, before the adhesive tape is put into use, it is necessary to conduct strict viscosity testing to ensure that it meets relevant standards and requirements.

[0003] Traditional viscosity testing methods rely heavily on manual operation and simple measuring tools, which is labor-intensive and cannot quickly measure viscosity at different locations during continuous tape winding. This results in a time-consuming and labor-intensive testing process, making it difficult to comprehensively assess the overall viscosity uniformity of the adhesive tape. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a viscosity testing device for automotive wiring harness adhesive tape, which solves the problem that traditional viscosity testing methods mentioned in the background art mainly rely on manual operation and simple measuring tools, which is laborious and cannot quickly test the viscosity at different positions during the continuous winding of the adhesive tape, resulting in a time-consuming and labor-intensive testing process and difficulty in comprehensively assessing the overall viscosity uniformity of the adhesive tape.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a viscosity testing device for automotive wiring harness adhesive tape, comprising a vertical plate and an adhesive tape body. A transverse main groove is formed on the surface of the vertical plate, and a slider is slidably connected to the inner side of the main groove. A rubber block is fixedly connected to the surface of the slider facing the adhesive tape body. The other side of the slider is fixedly connected to one end of a peak holding tension meter, and the other end of the peak holding tension meter is fixedly connected to one end of a pull rope. The other end of the pull rope is fixedly connected to the surface of a winding roller.

[0006] In this technical solution, the rubber block on the surface of the slider can simulate the rubber layer on the outer surface of the wire harness. After contacting the adhesive tape, the rope winding roller winds up the pull rope, thereby pulling the rubber block away from the adhesive tape. When the tape is broken at an instant, the peak holding tension meter records the data. Thus, the viscosity at different positions can be detected as the adhesive tape is continuously wound up, which is convenient, fast and improves the detection efficiency.

[0007] Preferably, a secondary sliding groove is provided on the surface of the vertical groove below the peak holding tension gauge, and a support block is slidably connected to the inner side of the secondary sliding groove. The support block is fixedly connected to the peak holding tension gauge.

[0008] Preferably, the rope winding roller is rotatably connected to the surface of the vertical plate, and a second servo motor is fixedly connected to the back surface of the vertical plate corresponding to the horizontal height of the rope winding roller. The tail end of the drive shaft of the second servo motor is fixedly connected to the rope winding roller.

[0009] Preferably, a guide wheel is rotatably connected to the surface of the vertical plate above the rope winding roller, the guide wheel is in contact with the rope, and the vertical plate is fixedly connected to the top of the base.

[0010] Preferably, a sub-frame is fixedly connected to the side wall of the slider, a side plate is fixedly connected to the edge of the vertical plate surface corresponding to the horizontal height of the sub-frame, and an electric actuator is fixedly connected to the surface of the side plate facing the sub-frame.

[0011] Preferably, a fixing plate is fixedly connected to the surface of the vertical plate on the left side of the main slide, a sleeve is rotatably connected to the surface of the vertical plate above the right side of the fixing plate, a take-up drum is rotatably connected to the surface of the vertical plate below the right side of the fixing plate, a No. 1 servo motor is fixedly connected to the back surface of the vertical plate corresponding to the horizontal height of the take-up drum, and the tail end of the drive shaft of the No. 1 servo motor is fixedly connected to the take-up drum.

[0012] Preferably, the adhesive tape body is sleeved on the surface of the sleeve, and one end of the adhesive tape body is fixedly connected to the surface of the take-up drum.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a slider on one side of the adhesive tape body. The rubber block on the surface of the slider can simulate the rubber layer on the outer surface of the wire harness. After contacting the adhesive tape, the rope winding roller winds up the pull rope, thereby pulling the rubber block away from the adhesive tape. When the tape is broken at an instant, the peak holding tension meter records the data. Thus, the viscosity at different locations can be quickly detected during the continuous winding of the adhesive tape, which facilitates the evaluation of whether the overall viscosity is uniform and improves the detection efficiency.

[0015] 2. This utility model sets a sub-frame on one side of the slider and sets an electric push rod at the horizontal height of the sub-frame. When the rubber block is detached from the adhesive tape, the winding drum winds up the position of the adhesive tape that has been detected, and the second servo motor is de-energized to stop winding. The electric push rod pushes the sub-frame and slider back to the adhesive tape until they stick, thereby detecting the viscosity at the new position. This is convenient and quick, and does not require manual adjustment of the adhesive tape, making it highly practical. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A viscosity testing device for automotive wiring harness adhesive tape, see [link / reference]. Figures 1 to 3 The device includes a vertical plate 2 and an adhesive tape body 5. A transverse main groove 7 is formed on the surface of the vertical plate 2. A slider 8 is slidably connected to the inner side of the main groove 7. A rubber block 801 is fixedly connected to the surface of the slider 8 facing the adhesive tape body 5. The other side of the slider 8 is fixedly connected to one end of a peak holding tensile tester 14. When testing is required, the rubber block 801 on the slider 8 is brought into contact with the adhesive surface of the adhesive tape body 5 until it is firmly bonded. At this point, the pull rope 12 pulls the peak holding tensile tester 14 and the slider 8. During the pulling process, the data from the tensile tester can be observed to determine the viscosity strength. The maximum reading at the moment of detachment can also be recorded. By comparing multiple sets of detected data, it is possible to clearly determine whether the overall viscosity of the adhesive tape body 5 is qualified. The testing is convenient and highly efficient.

[0023] Specifically, such as Figure 1 and Figure 3As shown, the other end of the peak holding tension gauge 14 is fixedly connected to one end of the pull rope 12, and the other end of the pull rope 12 is fixedly connected to the surface of the winding roller 15. The winding roller 15 is rotatably connected to the surface of the vertical plate 2. A second servo motor 151 is fixedly connected to the back surface of the vertical plate 2 corresponding to the horizontal height of the winding roller 15. The tail end of the drive shaft of the second servo motor 151 is fixedly connected to the winding roller 15. A guide wheel 13 is rotatably connected to the surface of the vertical plate 2 above the winding roller 15. The guide wheel 13 contacts the pull rope 12. The vertical plate 2 is fixedly connected to the top of the base 1. When the second servo motor 151 is started, it drives the winding roller 15 to rotate, winding the pull rope 12, thereby pulling the tension gauge and the slider 8. When the test is completed, the second servo motor 151 is de-energized. At this time, the winding roller 15 can rotate freely, which facilitates the release of the pull rope 12, allowing the slider 8 and the rubber block 801 to re-contact the adhesive tape.

[0024] Specifically, such as Figure 1 As shown, a sub-frame 9 is fixedly connected to the side wall of the slider 8. A side plate 10 is fixedly connected to the edge of the vertical plate 2 at the horizontal height of the sub-frame 9. An electric push rod 11 is fixedly connected to the surface of the side plate 10 facing the sub-frame 9. After the current position is detected, wait for the take-up drum 6 to rotate and pull the adhesive tape so that the new detection position reaches one side of the slider 8. At this time, the electric push rod 11 can be activated to push the sub-frame 9 and the slider 8, so that the rubber block 801 contacts the adhesive tape and is stuck. Then the electric push rod 11 retracts, and a new round of detection can begin.

[0025] Furthermore, such as Figure 1 As shown, a secondary slide groove 141 is provided on the surface of the vertical groove below the peak holding force gauge 14. A support block 142 is slidably connected to the inner side of the secondary slide groove 141. The support block 142 is fixedly connected to the peak holding force gauge 14. The peak holding force gauge 14 has its own weight. In order to avoid its own weight affecting the measurement data, the secondary slide groove 141 and the support block 142 are specially set to support it. When the peak holding force gauge 14 is pulled, the support block 142 will support it from below and slide along the secondary slide groove 141.

[0026] It is worth noting that, such as Figure 1 and Figure 3As shown, a fixing plate 3 is fixedly connected to the surface of the vertical plate 2 on the left side of the main slide 7. The fixing plate 3 facilitates the limiting of the adhesive tape body 5, thereby providing support when the electric push rod 11 pushes the sub-frame 9 and the slider 8, so that the rubber block 801 and the adhesive tape body 5 can be smoothly bonded together. A sleeve 4 is rotatably connected to the surface of the vertical plate 2 above the right side of the fixing plate 3, and a take-up drum 6 is rotatably connected to the surface of the vertical plate 2 below the right side of the fixing plate 3. The adhesive tape body 5 is sleeved on the surface of the sleeve 4, and one end of the adhesive tape body 5 is fixedly connected to the surface of the take-up drum 6. On the side of the vertical plate 2, which is at the same horizontal height as the take-up drum 6, a servo motor 601 is fixedly connected. The tail end of the drive shaft of the servo motor 601 is fixedly connected to the take-up drum 6. The adhesive tape body 5 is put on the sleeve 4, and one end of the adhesive tape body 5 is pulled out and stuck to the take-up drum 6. When the current position of the adhesive tape body 5 is detected, the servo motor 601 is started to drive the take-up drum 6 to rotate, thereby winding up the detected position so that the new detection position reaches the side of the slider 8, thus accepting a new round of detection.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
